Abstract
Probiotic bacteria have been commonly used for disease prevention in aquaculture systems, but sometimes these probiotic bacteria do not work in certain ponds. This experiment aimed to find out if the probiotic bacteria of Serratia marcescens MY1112 could work properly for tiger shrimp culture in acid-sulfate soil ponds. Eight 0.5-ha ponds located in Samataring village of Sinjai regency were used. Two treatments of bacteria probiotic combinations were applied here, namely A) Brevibacillus laterosporus BT951, Serratia marcescens MY1112, and Bacillus licheniformis BM58; and B) Use of Bacillus subtilis BM12 to replace S. marcescens MY1112 in the bacteria combination. The shrimp production and their survival rate in treatment A were significantly better than those of treatment B. However, probiotic bacteria of Serratia marcescens MY1112 could work better in the acid-sulfate soil pond if combined with the dolomite application weekly.
